HL7010

HL7010 is a simple fully integrated switch-mode Li-ion battery chargers providing 3.78A max charge current for single cells. The charge will charge the battery without power path management, which will provide low cost and compact charging solutions for smart phones, tablets, power banks and other portable devices. To further reduce the cost and size and increase the charging efficiency, the charger removes the current sense resistor and uses unique sense method to get accuracy charge current control. Internal power switches are optimized to get high efficiency with different input voltage which will reduce the charging time. HL7010 supports a wide range of input sources, including standard USB host port, USB charging port and AC-DC adapter. It supports an input operating voltage from 4.0V to 10V and can power up the system rail without a battery. It can support BC1.2 detection which can get proper input current limit to get full use of the power provided by the input source. HL7010 can manage the complete charging cycle of a Li-ion battery autonomously with the presence of an I2C host. It detects the battery voltage and automatically charges the battery in three phases: pre-charge, constant current, and constant voltage. It automatically terminates charging when the battery is fully charged and re-starts a charging cycle if the battery voltage falls below the recharge threshold. Its I2C interface provides maximum programmability for charging parameters and system-level communication. When the I2C host is not present, a built-in safety timer stops charging after the timer expires to assure safety battery operation. HL7010 supports OTG function which will provide configurable output voltage at VBUS, the max output current can get up to 1.6A. HL7010 integrates comprehensive protections mechanism to ensure safe operation, including input over voltage and under voltage, VBAT over voltage, inductor over current, thermal regulation and thermal shutdown etc. HL7010 is available in a compact 1.6mm x 2.0mm WLCSP-20 package.
